2. Right click the line of code mov W0,W14 and choose Run to Cursor. The green

to and including mov W0,W14.

3. From the View menu, select Watch to open a Watch window, and select

RCOUNT in the Add SFR pull-down list.

4. Click Add SFR to add the RCOUNT register to the Watch window.

5. Press <F7> a few times and watch the RCOUNT value decrement (see

Figure 2-16). RCOUNT is the repeat loop counter and decrements to zero as the

instruction in a repeat loop is executed several times.
